Question

In which stage of meiosis do sister chromatids separate?

Mr. NARESH KUMAR K · Accepted Answer

## CORE INFORMATION
✓ **Answer**: C
## CONCEPT FRAMEWORK
 **Primary Concept**: Meiosis
 **Related Topics**: Cell division, chromosomes, mitosis
 **Prerequisites**: Understanding of meiosis I and meiosis II, sister chromatids, homologous chromosomes.
## SOLUTION PATHWAY
**Given Information**:
  The question asks about the separation of sister chromatids during meiosis.
  Meiosis is a type of cell division that reduces the number of chromosomes in half.
**Method & Steps**:
 1. **Understanding Meiosis I and Meiosis II**: Meiosis consists of two rounds of division: Meiosis I and Meiosis II.  In Meiosis I, homologous chromosomes separate, while in Meiosis II, sister chromatids separate.
  Reasoning: Sister chromatids are identical copies of a chromosome joined at the centromere. They are created during DNA replication before meiosis.
  Formula/Rule: None directly applicable.
 2. **Identifying Sister Chromatid Separation**: Sister chromatids are separated during Anaphase II of meiosis.
  Working:  Anaphase I involves the separation of homologous chromosomes, not sister chromatids. Telophase stages are characterized by the completion of chromosome separation and the reformation of nuclear envelopes.
  Key Point:  The key difference between Anaphase I and Anaphase II lies in what separates: homologous chromosomes in Anaphase I and sister chromatids in Anaphase II.
 3. **Final Answer**: Anaphase II is the stage where sister chromatids separate.
  Result: Anaphase II
  Verification: Review the events of each stage of meiosis I and II to confirm.
 ## OPTION ANALYSIS
A :x: Anaphase I separates homologous chromosomes, not sister chromatids.
B :x: Telophase I is the final stage of Meiosis I, where the cell is nearly divided into two.
C ✓: Anaphase II is the stage where sister chromatids are separated to opposite poles of the cell.
D :x: Telophase II is the final stage of Meiosis II, similar to Telophase I.
 ## LEARNING AIDS
 **Common Mistakes**:
  1.Confusing Anaphase I and Anaphase II:  Remembering that homologous chromosomes separate in Anaphase I and sister chromatids separate in Anaphase II is crucial.
  2.Misunderstanding the role of Telophase stages: Telophase stages are the concluding stages of each meiotic division, not the stages where chromosome separation occurs.
 **Quick Tips**:
  1.Use mnemonics to remember the differences between Anaphase I and Anaphase II (e.g.,  'I' for 'Homologous' and 'II' for 'Sister').
  2.Draw diagrams of each stage of meiosis to visualize the chromosome movements.
